Biometrics
Once the stuff of Futuristics and science fiction, biometrics - the authentication of identity through an individual’s unique physical or behavioural traits has been hailed as one of the top 10 emerging technologies that will change the world. Common physical biometrics includes fingerprints, hand geometry, retina, iris and facial characteristics. Behavioural characteristics include signature, voice, keystroke pattern and gait. Iris-recognition based systems for access to high security areas and biometric signatures for speedy clearance of large quantities of cheques in a bank are already in use. The challenge lies in making them more userfriendly and fool-proof by minimising the FAR (false acceptance rate) wherein a wrong person is given access and FRR (false rejection rate) wherein the right person is denied access. An army of biologists, forensic and software experts are involved in research and development of new applications.
